HOOP-SPLiTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 298,044, dated May 6,1884.

Application filed February 29, 1F84. (No model.)

ple in its construction and thoroughly effective' in its operation. Y

A further object of the invention is to provide devices forautomatically feeding the strip of wood from which the hoops are to becut to the saw.

A further object of the invention is to provide a gage or marker wherebythe strip of wood from which the hoop is to be sawed is heldin placewith relation to the saw and a hoop of the desired thickness is cut.

Vith these ends in View the invention consists in the improvedconstruction and combinations of parts hereinafter fully, described, andpointed out in the claims.

In the drawings, Figure l is a perspective view of a machine constructedin accordance with my invention. Fig. 2 is a longitudinal verticalsection of the same, and Fig. Sis a transverse section just in rear ofthe saw.

In the accompanying drawings, in which like letters refer tocorresponding parts inthe figures, A represents the platform or frameupon which the mechanism is placed,and which consists of the top ortable B, having'side strips, C, and supported by suitable legs, C.

D represents a shaft which has bearing in the sides C, near the frontend thereof, the same passing below the top or table. Upon the end ofthis shaft D is rigidly mounted a pulley, a, which is adapted to receivea band, by which means said shaft is revolved. At about the center ofthis shaft is provided a corrugated disk, E, having a circumferentialgroove, b, the teeth of the saw revolving therein. This corrugated diskprojects upwardly,

or may be said to be 'so located as to extend through an opening,c,formed on the top or table. Upon the sides of this table are securedbrackets d, in which are mounted the ends of a shaft,F, having pulleysat theirends to receive bands or belts. At about the center of thisshaft F is rigidly mounted the saw, which is circular and of theordinary construction. Upon the forward end of the table B is'secured abracket, G, through which the strip of wood from which the hoops are tobesawed is passed, and which serves as a guide for the same.

H represents brackets or guides, which are secured to the top or tableB, adjacent to the opening of the same. These brackets or guides arebent rearwardly at theirforward ends, and the said ends held by means ofblocks c, operated by set-screws, by which means theends of the guidesmay be adj usted tothe thickness of hoop to be sawed and guide thesame'.

I represents a shaft having bearing in the sides of the supporting-framenear the rear end thereof, said shaft being provided at one of 'its endswit-h a rigidly-mounted pulley and at about its center with apinion-wheel, K,which is adaptedto mesh with rollers L, the bottom facesof which are geared. These rollers prov ject through an opening in thetable, and are formed at their upper ends with trunnions, which aremounted to revolve in a bracket, M. Upon one of the rear legs of thetable is secured a lever, N, which has connected thereto a'rope orchain, which passes through an eye or loop projecting downwardly fromthe under side of the table, and is connected to the roller which isfarthest therefrom, whereby upon said lever being depressed the saidroller is drawn close to and nearly in contact with the.

adjacent roller for a` purpose which will be explained.

Upon thetop of thetable B and near the rear end vof the same, adjacentto one of the rollers, is secured the end of a bar orrod, O, the end ofwhich is located adjacent to the saw.

The operation may be briefly described as follows: The strip of wood isfed to the saw passing between theguides H. Motion is imparted to theseveral shafts by bands or belts,

the power being applied first to the shaft car` rying the saw. As thematerial is fed to the saw, the corrugated roller, which is locatedadjacent thereto, feeds the strip, of wood forward, and the thin stripor hoop passes tothe left of the rod O, while the main piece passesbetween the rollers L, which, in conjunction IOO with the corrugateddisk on the forward shaft, serve to draw the strip forward, the saidrollers L being held in close contact with the strip by nieans ofthelever having the connecting-rope.

It will be seen that in lieu of pulleys connected by belts the ends ofthe several shafts may be provided with gears, which will accolnplishthe same result.

It will also be obvious that the machine above described iscomparatively simple, and that it is thoroughly effective and efficientin its operation.

Having fully described my invention, whatI claim as new, and desire tosecure by Letters Patent, is-

l. ln a hoop-sawing machine, the combination, with a suitablesupporting-frame, the top of which is formed with an opening ucar thefront end thereof, of a shaft carrying a corrugated disk located beneathsaid top and bearing in the sides-of the supporting-frame, a shaftmounted in brackets on the top of said table, guides H, secured at theirrcar ends near therear end ofthe corrugated disk, their other or freeends extending forwardly and then bent rearwardly to form a U shape, andblocks operated by set-screws for adjusting the same, substantially asset forth.

2. The combination, with a suitable supporting-frame the top of which isprovided with an opening near its front end, of a shaft carrying apulley mounted in the sides thereof beneath said table, said shaft beingalso provided with a 'corrugated disk having a circumferential groove, ashaft carrying the saw, adjustable guides H, secured adjacent thereto,and a bracket, G, secured to the table near the front end thereof,substantially as set forth.

3. The combination, with a suitable frame or support of a shaft locatedin the sides thereof, and provided at about its center with apinion-wheel, of vertical rollers the upper ends of which bear in abracket secured upon the table, and having their lower ends geared toengage said pinion, and a rod secured to the top of the table, its frontend extending forwardly adjacent to the saw, substantially as set forth.

4. The combination, with vertical rollers loosely mounted at their upperends, and adaptcdvto mesh with a pinion at their lower ends, of a lever,and a cord connecting said lever with one of said rollers, substantiallyas and for the purpose set forth.

5. lThe combination, with a suitable supporting-frame carrying acorrugated disk provided with acircumferentialgroove, and with a sawmounted upon a shaft suitably journaled, of vertical rollers looselyconnected at their upper ends, and adapted to mesh with a pinion-wheelat their lower ends, and a lever connected with one of said rollers,substantially as set forth.

6. The combination, with a suitable supporting-frame carrying acorrugated disk provided with a circumferential groove, guides locatedadjacent to said disk, and asaw mounted upon a shaft above said disk, ofvertical rollers located in rear of the saw, said rollers being looselyconnected at their upper ends, and adapted to mesh with a pinion attheir lower ends, a rope or chain connected to one of said rollers, alever for operating the same, and a rod secured adjacent to said rollersat its rear end, its forward end being located adjacent to thecorrugated disk and saw, substantially as set forth.

ln testimony that I claim the foregoing as my own I have hereto aiiixedmy signature in presence of two witnesses.

ISRAEL VALBORN.
